The Brazil international has missed training with a muscle problem but still has a couple of days to recover.
Midfielder Jordan Henderson (foot) and striker Daniel Sturridge (hip) are still sidelined but defender Dejan Lovren, an unused substitute last weekend, could return to the Liverpool side after injury.
Provisional squad: Mignolet, Clyne, Matip, Lovren, Milner, Can, Lallana, Wijnaldum, Mane, Firmino, Coutinho, Karius, Alexander-Arnold, Klavan, Moreno, Lucas, Stewart, Woodburn, Origi.
